Only global repositories, that is, visible by the same name from all script files, are supported. | |||
== | == Virtual devices == | ||
In previous versions of wb-rules, the values of virtual device controls were stored only in MQTT retained, which is not very reliable (in the case of | |||
power loss data could easily be lost). Starting with version 2.0, these values are also stored in a special permanent storage | |||
memory and restored when the script is loaded. | |||
If it is necessary to restore a strictly defined value (i.e. not to restore the previous saved value) every time the script is restarted, | |||
you can add the forceDefault field to the control description: | |||
<syntaxhighlight lang="js"> | <syntaxhighlight lang="js"> | ||

type: "value", | type: "value", | ||
value: "10", | value: "10", | ||
forceDefault: true // | forceDefault: true // every time the script box mycell will receive a value of 10 | ||
} | } | ||
} | } | ||
}); | }); | ||
